The overwhelming majority of traditions and Muslim scholars state that Adnan is a descendant of Kedar the son of Ishmael,[5][8][9][10][11] except for Ibn Ishaq who claimed that Adnan was a descendant of Nebaioth,[12] this confusion of Ibn Ishaq can be because one of the descendants of Kedar was also named "Nebaioth".[13]

Various genealogies of Adnan up to Isma'il have been narrated. Adnan was the ancestor of the Adnani Arabs of northern, central and western Arabia and a direct descendant of Isma'il. It is not confirmed how many generation are between them, however Adnan was fairly close to Isma'il. Isma'il had twelve sons who are said to have become twelve tribal chiefs throughout the regions from Havilah to Shur (from Assyria to the border of Egypt).

Genealogists differ from which son of Isma'il the main line of descent came, either through his eldest son Nabut, or his second son Qedar who was the father of the North Arabian Qedarite tribe that controlled the region between the Persian Gulf and the Sinai Peninsula. Genealogists also differ in the names on the line of descent.

Descent from Adnan to Muhammad[edit] According to Islamic tradition, the Islamic prophet Muhammad was descended from Adnan. "The following is the list of chiefs who are said to have ruled the Jazeera and to have been the intraline ancestors of Muhammad."
